sponding parts.

Our invention relates to an improved automatic car-coupling that couples in reliable manner without danger to the attendant; and it consists of a draw-head with inclined lateral lockingpiece and a swinging top hook that is raised or lowered for uncoupling and `coupling by a swinging bridge operated by a levera-rm of the shaft ofthe coupling-hook, so as touncouple simultaneously the coupling.

In the drawing, A represents a draw-head with closed or open top, which is provided near the middle part with a lateral inclined gate or piece, B, that may be slotted andper t'orated to admit the coupling ofthe draw head with the common pirrand-link drawheads. A coupling-hook, O, is pivoted to a lateral shaft, O', of the draw-head above the inclined gate, to pass up on the approach of the cars along the inclined piece B of the adjoining coupling until dropping back ofthe upper edge of the same and locking thereto. A rod, D, passes in longitudinal direction. through the shaft C of the coupling-hook C, and engages a side lug or pin, a, of the same by its front endan d a recessed arm, b, of a' swinging bridge, E, fulcrumed to the rear end of the draw-head by its rear end. The rod D The interlocking-hooks'ibrm a double reliable coupling of the cars, which hasrthe advansage of getting readily detached in case one of the cars is thrown oft' the track.

The rear part o'f the draw-head is applied by slot, pin, and cushioning-spring to a. drawbar applied in the customary manner to the bottom ofthe car. The draw-head has, thereby, greater side play, and is capable of resisting more fully the colicussions ofthe cars.

Having thus described our invention, what we claim as new, and desireto secure by Letters Patent, is'- The combination of open-topped draw-head A, the lateral, inclined, slotted", and perforated gate B, the coupling-hook C pivoted above said gate, and having lug c, the shaft C', the rod D, and the bridge E fulcrumed to rear end of draw-head, all substantially as and for the purpose specified.
